Abstract

The invention relates to the field of transparent conductive films, in particular to a composite transparent conductive film based on plant veins and a preparation method thereof. The composite transparent conductive film is formed by compounding the plant veins and silver nanowires-MXene through a deposition method. The method comprises the following steps: (1) etching plant leaves with a sodium hydroxide aqueous solution, removing mesophyll cells, washing with deionized water, and drying to obtain a plant vein substrate; (2) flattening the plant vein base to obtain a flat plant vein base; (3) soaking in a silver nanowire ethanol solution, drying to obtain a silver nanowire conductive layer, soaking the veins of the obtained silver nanowire conductive layer in an MXene solution, and drying; and (4) flattening the silver nanowire-MXene conductive network veins transparent conductive film obtained in the step (3). The conductive film has the characteristics of high conductivity, high light transmittance, high adhesion, high durability, high flexibility, high mechanical stability and the like, and has a wide application prospect in electronic device.

Description

technical field

[0001] The invention relates to the field of transparent conductive films, in particular to a composite transparent conductive film based on plant veins and a preparation method thereof. Background technique

[0002] Transparent conductive films are widely used in touch screens, organic light-emitting diodes, liquid crystal displays, solar cells, sensors, printable electronics and many other electronic devices. The flexibility and stability of transparent conductive films play an increasingly important role in the development of electronic devices. Most thin-film optoelectronic devices use sputtered metal oxide thin films as their transparent electrode materials. For now, the most widely used is the transparent conductive film based on indium tin oxide (ITO), which has been widely used in the past half century due to its good conductivity and transparency. business use. However, the disadvantages of indium oxide, such as brittleness, high-temperature depos...
